Nikolas Jacob Cruz became one of the most notorious mass killers in modern American history after carrying out the February 14, 2018, shooting at Marjory Stoneman Douglas High School in Parkland, Florida. Armed with a semi-automatic rifle, Cruz murdered 17 students and staff members and wounded 17 others before fleeing the campus, making it one of the deadliest school shootings in United States history. The massacre shocked the world and sparked an unprecedented movement led by student survivors demanding stronger gun laws and improved school safety. Cruz's history of behavioral problems, mental health concerns, online threats, and numerous contacts with law enforcement became central to public debate following the attack. The shooting permanently changed the national conversation surrounding school violence and mass shootings.

Patricia Dianne Krenwinkel was one of Charles Manson's most devoted followers and participated directly in the Tate-LaBianca murders that left seven people dead over two nights in August 1969. At the Tate residence, she chased and repeatedly stabbed Abigail Folger, and the following night participated in the murders of Leno and Rosemary LaBianca, later using their blood to write messages at the crime scene. Krenwinkel was convicted in 1971 of seven counts of first-degree murder and conspiracy to commit murder and sentenced to death, which was reduced to life imprisonment after California temporarily abolished capital punishment. She has spent more than five decades in custody, becoming California's longest-serving female prisoner. Although parole boards have repeatedly found her suitable for release in recent years, Governor Gavin Newsom most recently reversed a parole grant in October 2025, finding that she continued to pose an unreasonable danger to society.

Paul Edward Hicks became known in Ohio criminal cases after being convicted in 2025 for the 2001 murder of his estranged wife, Regina Rowe Hicks. The case remained unresolved for more than two decades before prosecutors finally secured a conviction, turning the investigation into one of the region’s most significant cold case homicide prosecutions. Born on July 18, 1955, in Willard, Huron County, Ohio, Hicks was accused of killing Regina during a period of marital separation and escalating personal conflict. Investigators later alleged he attempted to conceal the crime and avoid responsibility for years while the case remained unsolved. The eventual conviction drew major attention because of the extraordinary delay between the killing and the courtroom outcome, highlighting advances in investigative persistence, forensic review, and cold case prosecution strategies.
